Which of the following statements is wrong about the reaction.
It changes to +3 in
(reduction) (acts as oxidant)
Whereas O in CrO5 changes to O2
(oxidation) (acts of reductant)
So, CrO5 acts as oxidant and reductant both.
and also it is intramolecular redox reaction since in CrO5, both Cr and O undergoes oxidation and reduction reaction.
